To all whom it may concern: 7

Be it known that 1, DAVID M. KELSEY, a citizen of the United States, anda resident of Saratoga Springs, county of Saratoga, and State of NewYork, have invented a certain new and useful Composition of Matter to beUsed as a Deodorizer and Disinfectant, of which the following is aspecification.

My invention relates to a composition of to matter to be applied to thefloors of stables, ferry-boats, bridges, street hack-stands, or Whereveranimal excrements are deposited; and its object is to thoroughly andeffectively deodorize and disinfect such places. The odor arising fromthis composition when it is exposed upon the floor has a tendency tokill lice, flies, mosquitos, and all vermin that infest the atmosphere,and at the same time is not injurious to flesh,wool, hair, feathers, &c.My composition consists of the following ingredients, combined in theproportions stated and which are given in weight: hydrated calciumsulfate, seventeen parts; charcoal, two parts; dried peat, one part;sulfur, su blimed, three-tenths part; ferric oXid, onetenth part, andcrude phenic acid, thirty per cent., one twenty-fifth part. The firstfive ingredients are prepared by reducing to a fine powder. The acid andsulfur are then united,

0 this compound being then dried by the introduction of suficientcalcium sulfate for this purpose. The carbon is next introduced,followed by the remaining ingredients, the whole being reduced to ahomogeneous mass,

in which condition the compound presents the appearance of a drab orgray flour, slightly tinged with brown, of soft but gritty feeling, andwith a slight odor of theacid remaining.

The hydrated calcium sulfate above men- 40 tioned is made up ofthe'following constituentsin the proportions given: lime, 32.56 percent. sulfuric acid, 46.51 per cent.,and water, 20.93 per cent. 7

The proportions as herein stated may be varied slightly, according tothe analysis of the raw materials, as from time to time determined.

What I claim, and desire to secure by Let ters Patent, is-

The above-described composition of matter consisting of hydrated calciumsulfate, charcoal, dried peat, sulfur, ferric oxid, and crude phenicacid, in the proportions specified, substantially as described and forthe purpose specified.

In testimony that I claim the foregoing as my invention I have signedmyname, in presence of two witnesses, this 3d day of February, 1900.
